AX3121 3.5A Synchronous buck Converter  GENERAL DESCRIPTION AX3121 consists of step-down switching regulator with synchronous PWM converter. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and NMOS etc. AX3121 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to the duty ratio linearly form 0 up to 100%. This converter also contains an error amplifier circuit as well as an enable/soft-start circuit that prevents overshoot at startup. An enable function, an over current protect function and short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced. Also, an external compensation is easily to system stable.
